Perspective #139 – Some thoughts on Semi-Autogenous Grinding (SAG) Mills. Written by Richard Addison | Principal Process Engineer. This paper explores why SAG mills are an enigma when compared to ball mills, providing an in-depth analysis of how the advantages of SAG milling outweigh the shortcomings.

It can be very difficult operationally to trade grind for throughput in an SAG circuit—once designed and constructed for a given circuit configuration, an SAG mill circuit has limited flexibility to deliver varying product sizes, and a relatively fixed unit power input for a given ore type is typically required in the SAG mill.

This tool, according to RME, is suitable for larger mills. Each unit requires a Thunderbolt Power Pack to supply the electrical and hydraulic needs of the hammer and powered …

This design allows for addition of extra magnetic separators and eventually metal detector systems electrically interlocked with the movable feed gate to the screen (or crusher). In case metal objects are detected, they can be diverted directly back to the SAG mill. The designed grinding circuit, including the pebble crusher, is shown in Figure 2.

's AG/SAG mills accomplish the same size reduction work as 2 or 3 stages of crushing and screening The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an ...

This paper reflects on how measurements from inside an operating SAG mill might be used to better understand charge motion and energy dissipation within the mill. The paper discusses how the measurements might influence and enhance approaches to energy efficient mill operation when compared with current day modelling techniques. Insights …

performing SAG mill. It is possible in some cases to modify a SAG circuit to force it to perform better, but this often takes time, much effort and costly modifications. In most cases the capital spent on a properly sized SAG mill may prevent production losses that would be many times greater over the extended start up period.
